  1. //simple button GET server code to control servo and arduino pin 5
  2. //for use with IDE 1.0
  3. //open serial monitor to see what the arduino receives
  4. //use the \ slash to escape the " in the html
  5. //for use with W5100 based ethernet shields
  6. //Powering a servo from the arduino usually DOES NOT WORK.

So you can use any number from 192.168.1.1 to 192. 168.1.200 as long as they are not being used my any other device on you network. Use this ip when setting up port forwarding in the router for NAT-> port forwarding.
